There is a volcano in Naples called Mt Vesuvius and it is really dangerous

It exploded in 79AD

When it erupted in 79AD the ash from the volcano hardened around the buildings (making a cocoon) which preserved them for along time and with people the ash harden around the people when they were about to die

If you want to find out when volcanoes are likely to erupt you can look at the patterns of when a volcano has erupted and then see the time patterns

This Video was about Electricity and Electricity conductors and insulators

Steven Gray came up with the theory of conductors and insulators

A Hauksbee machine creates static electricity

To work out the theory he made a structure that was two swings made of wood with slick holding the structure in the air then he placed some gold leaves at the bottom then he generated electricity through the Hauksbee that when through a rod and into the structure which went through the boy and made the gold leaves come up to his hand and also feathers

This video was about how the United states did a world wide happiness test to see which is the happiest country

The scoring for the World wide Happiness test was between 0-10 in the leaderboard Australia was 9th under New Zealand. The happiest place was Norway because the people there live long lives, people trust the government and the government takes care of them. The lowest countries were parts of Africa and Syria because of war and governments that don’t have much money.

This video was about how people were having a debate over should we change our flag

The features of the australian flag are the Union Jack the southern cross and a star that represents the states and territories of Australia. People say that we should change the flag because it has nothing to do with aboriginals. People started to think about this because when people see the 3 flags [New zealand Australian and British] they straight away see the Union Jack which makes them think that those 2 other flags are british.British Australian New Zealand

If they did change the flag what would it look like?

If someone could change the flag would they keep the colors we have or change them?

This video was about how Human body parts can be replaced by Bionic parts and what difference there will be.

Bionic body parts replace other body parts the best thing is Australia came up with the bionic body parts,all together 60% of the human body can be replaced! and now we have 3D printing it’s way easier.

1. This video was taken in 2015 have any new bionic body parts been made since then?

2. Could you replace other animals parts like horses?

Making a bionic part may be hard but it is worth it

I took it a little further and looked up question number 2 but I couldn’t find anything about it but from what I read I thought the answer would be there still working on it
